I agree to an extent. Overtraining is very real and very possible to achieve but the term "overtraining" has been misused and abused for way too long.
It cracks me up when I'm getting ready to a 4th or 5th set of squats and one of the skinny fucknuts in my gym tells me I'm overtraining. WTF? (And this has actually happened before.) So let's compare quads then, buddy. I see lazy people use this as an excuse all the time. Usually the people who have enough mental fortitude, willpower, drive, and discipline to train like madmen also have the dedication to their diet and rest habits so that overtraining is never an issue with them anyway. For this reason, the majority of people that are yelling "overtraining" every other word are the ones who actually like the idea that, "Too much work at too much intensity will be detrimental." Hell, that's a lazy man's ideal statement! (Although it is true... TO A DEGREE!)
I can't speak for anyone else on this board but personally, I have always trained my balls off and I have NEVER felt any symptoms of overtraining!!! In fact, I've made steady good, gains over the years (drug free) and never once quit a workout too soon or didn't go to absolute failure for fear of the overtraining boogeyman.
Most spend too much time worrying about this bullshit...they'd be better off hitting it hard and saying to hell with overtraining. Kick some fucking ass in the gym...be a man! If you begin to overtrain...
you will know it!!! Trust me, the symptoms are not hard to recognize. If you're making gains, you can forget about worrying with this overtraining crap, jeeez!
For the last time:
Is overtraining real? Yes!
How many people actually do overtrain? VERY few.
We've been over this a million times on this board...
